Spitzer Space Telescope News

The Spitzer Space Telescope, part of NASA’s Great Observatories program, was launched in 2003 to study the universe in infrared light. This sophisticated observatory was designed to detect and study objects ranging from our solar system to the distant reaches of the universe, including remote galaxies, nascent star clusters, and nascent planets. Equipped with a cryogenically cooled telescope and sensitive instruments, Spitzer was pivotal in providing detailed imagery and data that helped astronomers understand the composition of celestial objects, map out star-forming regions, and observe the formation of galaxies. Although its cryogenic mission ended in 2009 when it ran out of coolant, Spitzer continued to operate until 2020 in a “warm” phase, still producing significant scientific insights with its remaining two channels.
